Answer 1

Explanation:

to get how far from the ground the top of the ladder is,we use sine.

sin = 65°

opposite= ? (how far the ladder is from the ground.)

hypotenuse=72 (length of the ladder)

therefore,

`sin65 = (x)/(72)`

x=7265

x=72×0.9063

x=65.25 inches (to 2 d.p)

therefore, the ladder is 65.25 inches from the ground.

to get the base of the ladder from the wall.

`cos \: 65 = (x)/(72)`

x= 0.4226 × 72

x= 30.43 inches to 2 d.p

therefore, the base of the ladder is 30.43 inches from the wall.
